Recent developments regarding ESK-001, an oral, highly selective TYK2 inhibitor being developed for moderate-to-severe plaque psoriasis, were presented at EADV 2024. TYK2 plays a crucial role in the cell signalling through cytokines such as IL-23 and IL-12, both of which are key players in the pathogenesis of psoriasis. ESK-001 aims to inhibit these pathways to offer an effective treatment option for patients. The STRIDE (NCT05600036) study, a phase 2 randomized, placebo-controlled trial, has already shown promising, dose-dependent efficacy, and the ongoing open-label extension study is assessing its long-term safety and effectiveness.
